足不出户 走遍全世界
一 | 英特尔提供的新编译器更新将协助为Sierra Forest CPU中看到的指令集带来介绍性的x86_64扩展，这将可以为操作系统产生准确的核心数。英特尔研究员和工程师Haochen在为Raptor Lake单独发布GCC编译器补丁后，率先发布了Meteor Lake补丁。然而，这两个补丁的修复并不算大，因为这些变化对两种架构的整体性能来说并不是高度不可或缺的。 CVS Health is planning to remove one type of a common decongestant from shelves after an advisory committee to the U.S. Food and Drug Administration said it was ineffective earlier this year.The products contain the oral formulation of phenylephrine (PE), which is found in several over-the-counter (OTC) medications.Although PE has been used as a decongestant for nearly a century, experts have been questioning its efficacy for years.The FDA Nonprescription Drugs Advisory Committee unanimously voted in September that PE did not improve nasal congestion any more than a placebo at the dosage given for OTC use.In response, CVS said it is removing products, in which PE is the only active ingredient from store shelves. This means products like Dayquil, which used a combination of active ingredients, will remain available for purchase."We are aware of the FDA Advisory Committee's position on oral phenylephrine (PE) and will follow direction from the FDA to ensure products we sell comply with all laws and regulations," CVS Health said in a statement. "We are removing certain oral cough and cold products that contain phenylephrine as the only active ingredient from CVS Pharmacy stores. Other oral cough and cold products will continue to be offered to meet consumer needs."CVS did not give specifies on brands that will be removed.The FDA told ABC News it has not yet determined whether it no longer considers PE to be a safe and effective medication and has not ordered the product to be removed from shelves. CVS's move is voluntary."The FDA has no further information to provide at this time regarding the timing of any decision the agency may make following the advisory committee meeting," the federal health agency said.The Consumer Healthcare Products Association told ABC News that the advisory committee's recommendation is a non-binding decision and not a change in regulation."FDA is currently in the process of reviewing the regulatory status of oral phenylephrine (PE) following September's advisory committee meeting," CHPA said in a statement. "Until FDA makes a determination on the committee's recommendation, oral PE remains a Category 1 OTC ingredient, which is generally recognized as safe and effective."Concerns were first raised about PE in 2007. Since then, evidence has accumulated showing that the drug offers little to no relief for nasal congestion.Experts believe this is because the body processes the drug before it reaches the nasal passages where it needs to work.It's unclear if other major retail pharmacy chains will follow in CVS's footsteps.Walgreens Boots Alliance would not disclose whether it was planning to remove products with PE from store shelves and said it would defer to the FDA."Walgreens follows FDA regulations. We are closely monitoring the situation and actively partnering with the Walgreens Office of Clinical Integrity and suppliers on appropriate next steps," a Walgreens spokesperson told ABC News.Other major pharmacy chains including Albertsons, Costco and Kroger did immediately reply to ABC News' request for comment. Walmart did not have an answer immediately available.ABC News' Sasha Pezenik and Sony Salzman contributed to this report.。英特尔的至强服务器系列CPU严格依赖E-cores，Sierra Forest也被纳入最新的更新中，其中大部分工作对改进更为关键。首先，"sierraforest"编译器目标被启用，以便为下一代服务器处理器提供进一步的指令，例如：AVX-IFMAAVX-VNNI-INT8AVX-NE-CONVERTCMPccXADDPhoronix网站的Michael Larabel从GNU项目网站上恢复了这个列表，同时还有来自英特尔的这个编程参考，以提供关于新指令的信息。x86_64 ISA编程参考手册的截屏前三条指令主要是针对AVX-512视频编解码器，第一条涵盖了整数融合乘加指令，而矢量神经网络指令则利用了INT8推理。AVX-NE-CONVERT通过从m16转换将BF 16 FP元素安装到FP32。最后，CMPccXADD代表"Compare and ADD if Condition is Met"，这是AVX-512在这个GCC补丁系列中的最后一套指令。
二 | Larabel指出，新的更新仍然可以集成到GCC 13编译器中，该编译器计划在2023年发布，在今年晚些时候的Ubuntu 23.10之后。对英特尔来说，这个时机将是完美的，因为该公司将在2023年第四季度发布用于数据中心的Sierra Forest处理器。了解更多：https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603542.html
